When checking collisions, the SHAPE_POLY_SET::Collide() routine is not
const because it will regenerate the triangulation cache if it is out of
date (using a const_cast, grrr). This sidesteps the issue by assigning
a mutex to the triangulation caching
Fixes https://gitlab.com/kicad/code/kicad/-/issues/17180
SHAPE_LINE_CHAIN_BASE can include things that are not SHAPE_LINE_CHAIN
like the triangle SHAPE_LINE primitive. To check arcs, we need to avoid
these elements as they do not have the full SHAPE_LINE_CHAIN class
available.

The clearance between two zones could be rather slow. This was in part
to trying to do triangle-triangle collisions between zones when we only
need outline collision and in part to the shape_line_chain collision
routine. The shape_line_chain collisions don't need to recreate
segments on each iteration and should instead create them once and using
this to check all collisions
Fixes https://gitlab.com/kicad/code/kicad/-/issues/17327
Also fixes length preview when hovering over joints.
Also prevents asserts when hovering over arcs.
Also prevents adding a tuning pattern on other tuning pattern.
(cherry picked from commit 711c6141a8)
Allow for overlapping points in input polygon. This is relatively
common on a grid and should be used as potential split points to shave
additional ears
Fixes https://gitlab.com/kicad/code/kicad/-/issues/16933
Failed triangulation can have multiple causes but we don't have another
approach, so skipping the cache just causes the same issue to be raised
again and again
Fixes https://gitlab.com/kicad/code/kicad/-/issues/16946
This maintains the primary goal of ensuring that bad splits do not allow
the triangulation process to continue. Instead, we boot this back up to
the top-level where we will simplify the polygon before triangulating
again.

- Avoid double-splitting a single point
- Check for mid-line intersections
- Avoid splitting zero-area polygons
- Keep full z-list for intersection checks
Fixes https://gitlab.com/kicad/code/kicad/-/issues/16241
It happens when the segment (aStart, aMid) is horizontal
Probably also when the segment (aEnd, aMid) is horizontal
Slopes with value 0.0 are set to double:: epsilon(), but it was a too small values
generating broken calculations.
Now set to 1e-10 (it seems working).
